The Angels had tried to get Santiago from the White Sox for infielder Howie Kendrick, but Chicago said no.

Trumbo would play the outfield for the Diamondbacks. It is unclear what other players -- likely prospects -- would be involved in the deal.

The Angels are strapped for pitching and money; the proposed trade would help in both respects. Neither Skaggs nor Santiago is eligible for salary arbitration, but Trumbo is, so the Angels' payroll would decline modestly, leaving budget room for midseason additions.
